Beyond the Code

Life's best moments happen away from the screen. Here's a glimpse into the people, places, and passions that keep me grounded and inspired.

Wedding celebration 2023

Best day ever! Marrying Amelia in 2023 was just the beginning of our adventure together. She somehow manages to put up with my coding marathons and still brings me coffee at 2 AM.

Bernedoodle dad moments

Meet Swish, my Bernedoodle and self-appointed Chief Debugging Officer. He has zero coding skills but somehow always knows when I need a walk break. Those puppy eyes are dangerously effective at ending late-night coding sessions.

Austin Texas lifestyle

Born and raised in Austin, where breakfast tacos are a food group and "Keep Austin Weird" isn't just a slogan. This city taught me that the best solutions often come from the most unexpected places.

Sports fan life

Football season is the best season for me - Texas Longhorns for college, Atlanta Falcons for NFL. Yes, I chose pain with the Falcons, but loyalty runs deep. Hook 'em Horns and Rise Up, always!

Trinity University graduation

Trinity University, Class of 2022. Four years of discovering that data tells stories, technology solves problems, and sometimes the best insights come from combining business and sports analytics in unexpected ways.
